A little test that does the browse page view on messages that are paged would be a good start point to be able to compare the responsiveness of getting the 100th page when we start at 0 or 100*pageSize.

Do you mean the current browse(int page, int pageSize, String filter) starts at 0? Because when I look at the code:

{code}

long start = (long) (page - 1) * pageSize

{code}

It seems like it starts at 99*pageSize (taking your example, getting the 100th page).

> The implementation of the paged browser creates a browser iterator and searches from the start for each page contents. It wold be better if it was possible to jump right in. Especially when messages are not in memory, ie: address limit has caused paging.
